COOLING SYSTEM OPERATION

!CAUTION

To prevent compressor and/or property damage, if power to the compressor has been off or interrupted for more than 1 hour and the outdoor temperature is be- low 50°F, DO NOT operate the system for at least the amount of time the compres- sor was off! This will allow the compres- sor heaters to warm the compressor oils to avoid damage due to slugging.

abled by pressing	SYSTEM	until AUTO is displayed
